Response class does not set headers

[dev-marcel]

In the Response class the function send() dus not do anything with the header array set in the construct. So no headers are set by sending the response.

See Application/Responses/Response.php on line 55.

Add:

//Set all headers defined in headers array
if(!empty($this->headers) and is_array($this->headers)) {
foreach($this->headers as $header) {
header($header);
}
}
